Suppose there is a claim that a certain population has a mean, u, that is different than 5. You want to test this clairn. To do so, you collect a large random
sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis H, and the alternative
hypothesis H, as follows.
H: u=5
H: u+5
Suppose you also know the following information.
The critical values are -1.645 and 1.645 (rounded to 3 decinal places).
The value of the test statistic is -0.809 (rounded to 3 decimal places).
(a) Complete the steps below to show the rejection region(s) and the value of the test statistic for this test.
Standard Normal Distribution
Step 1: Select one-tailed or two-tailed.
O One-tailed
O Two-tailed
Step 2: Enter the critical value(s).
(Round to 3 decimal places.)
0.2
01-
Step 3: Enter the test statistic.
(Round to 3 decimal places.)
